Willpower didn't do much for me either Scared, eventually in isolation my addiction would grind me down, sell me every good reason why I should drink and then I would give in, went round and round that merry-go round for years.
The trick for me was to not rely on willpower alone, daily support in the form of SR continued to give me a second opinion on things, got me outside of my own head.
Sobriety for me came down to action, changing things up, my routines, my lifestyle, getting a plan together, getting support around me, not continuing on and hoping for the best, as that never worked!!
You can break this cycle too!!
